arm64: dts: ti: k3-{j784s4-j742s2/j721s2}-mcu-wakeup: Add HSM M4F node

Browse source 
The TI K3 J721S2, J784S4 and J742S2 SoCs have a HSM (High Security
Module) M4F core in the Wakeup Voltage Domain which could be used to run
secure services like Authentication. Add Device Tree Node definitions
for the HSM core in the respective SoC wakeup dtsi files.

The HSM node is reserved to be loaded and booted by the early-stage
bootloader. The firmware-name property is defined at the SoC level
since the HSM is not a general-purpose remote core and boards are
unlikely to use separate firmware. If needed in exceptional cases,
board-specific device trees can override this property.
